The main fallacy in what is up here so far is the idea that Brian Wilson and The Beach Boys are interchangeable. While Brian was responsible for a lot of the best work, like Pet Sounds and Smile, much of the early 70s material with Carl and Dennis at the helm is truly excellent too - and Carl Wilson had one of the all time great rock & roll voices.

As well as their albums as a group, all the members of the Beach Boys have made solo albums. Here's a list of all the solo albums by members of the classic line-up. David Marks, Blondie Chaplin and Ricky Fataar are not included because they were not in the band for long enough periods, and appearances on other people's albums, and side-projects like Mike Love's Celebration, or The Legendary Masked Surfers are not counted unless noted.

Dennis and Carl Wilson and Mike Love's solos are all out of print currently.
Also the compilations Endless Harmony and Hawthorne, Ca are largely composed of otherwise unreleased material. A good overview of the band's career is provided by the box set Good Vibrations: 30 Years Of the Beach Boys and the box set The Pet Sounds Sessions contains much material that is unavailable elsewhere. More information about line-up changes and so on can be found at the nodes for individual albums, which detail their making.
